Convert PTIF to RAS

The PTIF (Pyramid Encoded TIFF) file format, developed by Image Magick, is a specialized variant of the TIFF image format designed to store multiple resolutions of the same image within a single file. This enables efficient zooming and panning in applications without losing image quality. PTIF files are commonly used in geospatial imaging, remote sensing, and medical imaging due to their ability to handle large, high-resolution images efficiently. The format was introduced to address the need for handling large image datasets more effectively in these fields.

The Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
